To all whom it may concern:

Beit known that I, JAMES A. GRAY, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, haie invented certain new and useful Improvements inApparatus for Cutting and Applying Ring-Liners to Can- Covers, of whichthe following is a specification.

The present invention relates to an improved m'achine for cutting ringliners from a traveling web of paper, depositing the same Within a seatof a rotary carrier, supplying a can cover within said seat of thecarrier in advance of thering liner, and forcing the placed ring linerwithin or onto the flange of the can cover, the various steps in theoperation of the machine being auto matically and successively carriedout through the action of a series of inter-connected 'instrumentalitiesso arranged relative to each other and timed as to their action ofmovement as to come into play at predetermined moments; the object ofthe invention being theproduction of an automatically operated machinefor the cutting and placing of the ring liners relative to the can coverwhich shall be simple of c0nstruction, positive in its action, durableand composed of comparatively few working parts.

To comprehend the invention, reference should be 'had to theaccompanying sheets of drawings, wherein Figure'l is a plan view of theimproved machine disclosing the relative position of the cutting punchfor severing the ring liners from the traveling web, the mechanism forimparting reciprocating motion thereto, the barrel or magazine forreceiving the central disk severed from the traveling web in the cuttingof the ring liners. the mechanism for delivering the can'covers to therotary carrier (not shown) the disposition of the web of paper fromwhich the ring liners are cut, the means for feeding the web acrossthefront of the cutting punch, and the feed mechanism for the can covers.Fig. 2 is a longitudinal sectional view taken on line :P:n Fig. 1 of thedrawings, viewed in the direction of the arrow 0, illustrating moreparticularlv the drive mechanism for imparting reciprocating movement tothe cutting punch and transmitting an intermittent or step rotation tothe carrier for the can covers and ring liners.

and the means for actuating the reciprocal?- ing plungers for forcingthe ring liner ontothe circumferential flange of the can covera. Fig. 3is-a vertical sectional view taken on line y-y Fig. 2 of the drawings,the barrel or magazine for the central disk cut from the traveling webbeing removed and the Web of paper being partly broken away, said viewdisclosing the rotatable carrier for the .can covers and ring liners,the means for delivering the out ring liners to the seats of the saidcarrier, the feed mechanism for the can covers, the position of thetraveling web, the feed means for advancing the web through the machinein advance of the cutting punch, and the discharge runway for the linedcan covers. Fig. 4 is a detail view of one of the cut ring liners. Fig.5 is a cross sectional view of one of the'can covers, within thecircumferential seat of which formed by the inturned edge of the flangeof the can cover is forced the ring liner. I In the drawings, thenumeral 1 is used to designatany suitable form of a supporting framecapable of sustaining the various working parts of the apparatus, and 2a bed mounted thereon and within guide ways 3 of which works thereciprocating slide 4 carrying at its inner end a detachable punch 5,and a die ring 5, Figs. 1 and 2 of the drawings. The said slide 4 isactuated by a cam 6 acting against rollers 7 and 7 mounted within across head 8 secured to and carried by the outer end of the slide r, thesaid actuating cam 6 being mounted on a crossshaft 8'- working inbearing boxes 9.

Between the punch 5 and the die ring 5' screwed to the slide 4 there isinterposed an ejector ring 5*, which is permitted slight movement underpressure of the punch 5.

From the said ejector. ring projects a series of bolts 0 which extendthrough bores in a circular shoulder (Z of the reciprocating slide 4 andact against a collar c slidably mounted on said slide and which isengaged by a finger 7" fixed to and upwardly projecting. from the frameof the machine on the return stroke of the slide 4 to force the ejectorring a slight distance beyond the die ring 5 to force the cut ring linerfrom off the punch.

The shaft is driven in any suitable manner, pret'trably by means of apower belt working over a belt pulley 9' secured to one end thereof, thesaid shaft at its opposite end carrying a gear wheel 10 which mesheswith a gear 10 for transmitting rotation to a cross shaft 11 situatedbelow the shaft 8 for imparting motion to the hereinafter describedactuating means for giving a step rotation to the carrier'containing thecan covers and liner rings to be applied thereto.

In front of the punch 5 and held a slight distance therefrom issituateda die ring 12, the same being loosely held to the innerend of acylindrical magazine 12 and normally held outwardly pressed by thesprings a, the magazine being attached to the frame of the machine, andin line with the punch 5 to receive the waste material or central diskcut from the web out of which the liner rings are formed, the die ring12 being held to the magazine 12 by the securing collar 6 united in anysuitable manner to the said magazine.

' The paper web 13 out of which the ring liners are cut is fedtransversely through the machine between the punch 5 and the maga- Zine12 by means of the vertically disposed guide feed rollers 13 and 14, thesaid web unwinding from a spool 1% loosely mounted on a short verticalstud 15 situated at one side of the bed 2 of the frame 1Figs. 1 and 3 ofthe drawings. The guide roller 13 a positively driven one, while theroller 14 is loosely mounted on a stud 1 upwardly projecting from aslide rod 14 and is frictionally driven, and the said roller 13 isdriven by means of a bevel pinion 15. secured to the lower end thereofmeshing with a bevel pinion 16 on a longitudinally disposed shaft 16working in bearing 17 at one side of the machine. This shaft .16 at itsouter end carries a bevel pinion 17 which is engaged and driven by abevel pinion 18 on the rotating cross shaft 11, having rotation impartedthereto from the drive shaft 8 through the described gear connections.

The web 13 is advanced through the machine only when frict ionallyengaged by the guide and feed rollers 13 and 14, but the travel of theweb is an intermittent one due to the fact that the roller 14: is onlyin engagement therewith at pre-determined moments, being normally heldout of engagement or away from the surface of the web by the tension ofthe spring 13 connected to and acting against the slide rod 1%. At itsouter end the said slide rod carries a roll 13 loosely mounted on alaterally projecting stud 13 and said roll is intermittently engaged bya cam 15 on the drive shaft 8 acting thereagainst. When the cam 15* actsagainst the roll l3 the slide rod 14 is forced forwardly, carryingtherewith the guide feed roller 14- for frictional engagement with theweb 13. which is then firmly tudin-allydisposed shaft 19, carrying atits inner end a bevel pinion 20 meshing with a similar pinion 20 on thelower end of a short vertical shaft 21. This shaft at its upper end isprovided with a gear 22, which meshes with and imparts rotation to agear ring 22 encircling the lower end portion of a can head holder 23,and said ring in turn meshing with a gear 23 imparts rota tion to ashort vertically disposed shaft 24- carrying a screw disk 24, acompanion screw disk 25 being secured to the short vertical shaft 21 towhich is attached the gear 22 and the bevel pinion 20. The said screwdisks 24: and 25 are located below the'bottom of the can head holder-28and serve as a screw feed means for delivering the horizontally disposedcan covers or heads 26 from within the holder 23 into a downwardlyinclined chute or runway 26, the said heads or covers as they leave thescrew feed bearing-against a bridge piece or plate 27 located within theupper portion of the chute or runway 26 and are thrown from a horizontalinto a vertical position-Fig. 3 of the drawings...

Within the frame of the machine and on a-lbngitudinal shaft 28 workingin bearings 28 thereof is situated a vertically disposed rotatablecarrier disk 29, whose movement in the direction of its rotation isdesignated by arrow a on Fig. 8 of the drawing, and the said carrierdisk is provided with a plurality of transversely oircumferentiallydisposed openings or seats 30, within each of which work a pair ofopposing normally spaced hollow reciprocating 'plungers 31 .seats 30 isintersectedby a segmental pe ripheral opening 34, and a similar opening3 1 through which the ring liners35 and the can covers' 26 respectivelyare deposited vertically within the seats 30 between the opposing facesof the plungers 3l and 3 2, 1

the can htfldS 01" covers 26 being delivered cover and ring liner standin vertical position between the plungers'31 and 32 and in front of thespring held chuck 31 of the .plu'nger 31, with the ring liner in advanceof and in alinement with the flange 26 of the cover 26, so that on theplunger-s being brought together the said ring liner 35 will be forcedonto the circumferential flange of the can head or cover 26, duringwhich seating of the ring liner the chuck 31 is gradually moved withinthe plunger 31.

By reason of the disposition of the cam grooves 33 of the fixed disks 34the plungers are held in such inwardly pressed position until by therotary movement of the carrier disk the rolls 33 are carried within theoutwardly extended portion of vthe cam grooves, by which time-theopening 34' of the seats 30 will be in line with the discharge runway 36and the plungers or pistons 31 and 32 moved away from each other orseparated. when tension of'the springs 36 coming into play forcesoutwardly the chuck 31 to unseat the can head or cover 26 with itsapplied liner ring, and place the same immediately over the opening 3ithrough which the same escapes by gravity into the discharge runway orchute 36 for delivery to a suitable place of deposit.

An intermittent or step rotation is 1mparted to the shaft 28 and thecarrier disk 29 secured thereon by means of the mutilated worm gear 37secured to the outer end of the shaft '28, which worm gear isintermittently engaged and given a part rotation by the worm section 37'of a disk 38, secured to the drive shaft 11 meshing therewith atgivenintervals. The rotary motion of the driveshaft is thus transmitted tothe shaft 28 and the carrier disk 29 for imparting a step orintermittent rotation thereto.

During the forward stroke of theslide 4 thepunch 5 and die ring actingagainst the web 13 forces the same firmly onto the 1agar.ine 12', thepunch 5 acting first to cut the central disk from the web and the diering 5 associated with the punch 5 by the continued movement of th slide4 ('(i acting with the die ring 1? cutting tho ring liner from the web13. the removed cen tral disk or body of the ring moving in o themagazine 19'. The liner ring adher s to the die ring 5 until on theoutward stroke of the slide 4 and punch 5, the collar 6 engages with thebracket 7', forcing the ejector ring 5 beyond the face of the die ring5" and punch 5 to release the cut liner ring 35, which escapes into andthrough the guide-way 38 and is deposited into one of the seats 30 ofthe carrier disk through the opening 34' communicating therewith. On theoutward or return stroke of the unching mechanism, the feed devices fort e web 13 advance the same to place or position an uncut portionthereof in advance of the punch mechanism, the saidoweb remaining atrest during the cutting stroke of' the' punching Inechanism,.whichintermittent or step feed movement of the web-13 is controlled by thebefore 'lescribed interconnected devices.

The working. stroke of the punching mechanism. the movement of theintermittent traveling web, the rotation of the carrier disk, and thefeed mechanism for the can heads or covers are so controlled, regulatedand timed with respect to eaolrother that the various described actionssuccessively come into play at predetermined moments, so that each partperforms its desired work at the proper moment with respect to the otherworking parts of the apparatus, thereby constituting an automaticmachine for cutting liner rings, assembling can heads or covers and theliner rings, forcing the liner rings onto the flange of the can heads orcovers, and discharging the can heads or covers with the ring linersapplied thereto.

I am aware that various changes may be made in the working parts and thedetails of construction herein shown and described without causing adeparture from the spirit of the invention, and I do not wish to beunderstood as so restricting, limiting or confining the invention, buton the contrary desire to cover the invention broadly irrespcctive'ofthe details of constrution of the working parts of the apparatus forcarrying the same out; although the arrangement and construction of theworking parts shown and described is preferred.
